Description
The 5110 spectrometer optical system features a temperature controlled purged optics
assembly allowing analysis over a full range of wavelengths from 166.798 nm to 784.307 nm.
The optical system of the Agilent 5110 spectrometer accepts light radiated from the plasma
and separates it into discrete wavelengths.
The 5110 spectrometer optical system construct includes:
• Polychromator heater box
• Pre-optics assembly
• Echelle polychromator assembly
• Camera assembly
